From the American Chemical Society. I wonder if they studied how much methane comes from sediment loads dropped by rivers naturally and compared them? The Mississippi Delta alone must be a terrible offender. Sediment trapped behind dams makes them ‘hot spots’ for greenhouse gas emissions With the “green” reputation of large hydroelectric dams already in…

This is sure to get some enviros in a tizzy. From Chemical and Engineering News of the American Chemical Society: Nuclear Power Prevents More Deaths Than It Causes Climate Change: Study estimates that nuclear energy leads to substantially fewer pollution-related deaths and greenhouse gas emissions compared with fossil-fuel sources By Mark Schrope Using nuclear power…

From the American Chemical Society Green plants reduce city street pollution up to 8 times more than previously believed Trees, bushes and other greenery growing in the concrete-and-glass canyons of cities can reduce levels of two of the most worrisome air pollutants by eight times more than previously believed, a new study has found. A…

From the University of Calgary New model provides lifecycle analysis of ‘well-to-wheel’ oil sands emissions Policy makers need to be cautious in setting new ‘low-carbon’ standards for greenhouse gas emissions for oil sands-derived fuels as well as fuels from conventional crude oils University of Calgary and University of Toronto researchers say in a paper published…

From the American Chemical Society it seems that newer is not always better. Even Yale environment360 bought into this idea. I should add that I’m all for reducing carbon soot, but in the zealous rush for solutions, sometimes too many cooks spoil the soup. Right: Primitive stoves and open fires pose serious health risks, particularly…

Great, just great. Don’t get me wrong, I like the LED bulbs, I have several in my house. But when we get back to basics, a tungsten light bulb doesn’t require a haz-mat squad to dispose of. It’s glass, ceramic, tungsten, some thin steel, and tin solder (if ROHS). CFL bulbs and now LED bulbs…
